What is the equation of a line with a slope of -8 and an ordered pair (4,-3)?

lisabon 2012 [21]

You can solve this easily using point slope form: y-y1 = m(x-x1)
Substitute the given y value in for y1 and the given x for x1, and substitute the slope in for m.
To put it in slope intercept form, isolate y.
Hope this helps!

Find (a) the circumference and (b) the area of the circle. Use $3.14$ or $\frac{22}{7}$

ohaa [14]

Answer:

$circumference = 2 \pi r = 2 \times 3.14 \ times 1 = 6.28m\\\\Area = \pi r^2 = 3.14 \times 1 \times 1 = 3.14m^2$

Write an equation in slope intercept form for the line that passes thru the points (4,-2) and (-5,7)

shepuryov [24]

Answer:

y = -x + 2

Step-by-step explanation:

The equation of a line in a slope intercept form is given as :

$y = mx + c$ , where m is the gradient and c, y - intercept.

First, let us find the gradient, m of the line that passes through the points, (4,-2) and (-5,7) using the relation ;

$m = \frac{y_2 - y_1}{x_2- x_1}$

By substitution we get

$m = \frac{7- (- 2)}{ - 5 - 4}$

$\implies m = \frac{7 + 2}{ - (5 + 4)}$

$\implies m = \frac{9}{ - 9} = - 1$

We substitute any of the points and the value of m into y= mx + c to find the value for c.

$\implies - 2 = 4( - 1) + c$

$\implies - 2 = - 4+ c$

Adding 4 to both sides.

$\implies 4- 2= - 4 + 4+ c$

$\implies 4- 2= + c$

$\implies c = 2$

Hence the equation of the line is :

y = -x +2

Each brochure is 23 centimetres wide.

RideAnS [48]

Answer:

6 brochures

Step-by-step explanation:

Each brochures is 23 centimeters wide.

The table is 1.5 meters wide.

To know how many brochures can be placed side by side on the table first you have to calculate how many centimeters there are in 1.5 meters wide.

One meter equals 100 centimeters.

Therefore in 1.5 meters there are:

$1.5*100 = 150$ centimeters.

Now we must calculate in how many parts of 23 cm can be divided 150 cm.

To do this we made the division of 150 between 23

$\frac{150}{23}= 6.522$

This means that up to 6 brochures of 23 cm can be placed side by side on the table
